QTR-Quadtone RIP

Hi,

   I am about to begin testing Piezography inks on Epson printers and after some searching, I see that some mac users are having problems with newest Mac OS/QTR/Piezography.  On Piezography's Facebook page, Jon Cone talks about QTR's upcoming release of their product as a standalone RIP (as opposed to a printer driver).   I'm in a busy production environment and don't really want to invest the time of familiarizing myself with the QTR print driver if a standalone RIP is imminent.  Any news on a release date?

Thanks,

   Adam Sanders
